Forest River Unveils All-New Sierra & Sandpiper Fifth Wheel Floorplan
Forest River recently announced the all-new 3900HBLR floorplan from its Sierra and Sandpiper fifth wheel brands. Forest River said the 3900HBLR brings a new level of freedom, comfort and modern convenience to RV living, whether RVers are chasing new horizons or simply craving a more elevated way to experience the road.

With more than 30 years of experience designing RVs for real-world travel and adventure, Sierra and Sandpiper have earned a reputation for blending dependable craftsmanship with smart, livable design, the company said. The 3900HBLR continues that legacy, giving today’s travelers a space that feels more like a high-end suite than a camper.
Work, relax and entertain wherever you are.
Inside, the 3900HBLR adapts to your lifestyle. A built-in mobile workstation and Wi-Fi router with booster make remote work and learning effortless. When it’s time to unwind, travelers can stretch out on the chaise longue, flip on the 65-inch backlit TV and enjoy the warmth of a 60-inch fireplace — all surrounded by sleek, modern finishes. Hidden storage solutions, like a pantry tucked behind the entertainment center, ensure that everything has its place without sacrificing space.
A kitchen designed for real cooking and real connection.
From morning coffee at the dedicated coffee bar to hosting friends for dinner, the chef-style kitchen and expansive butler’s pantry deliver the storage, prep space and high-performance appliances RVers need to cook — and live — without compromise.
Rest easy every day on the road.
With both a full and half bathroom, a king-size bed and a walk-in closet, the 3900HBLR ensures your day begins and ends in complete comfort, Forest River said. A washer and dryer make extended travel feel just like home.
Easy travels, thoughtful touches.
From the dual awnings that create instant outdoor living space to auto-leveling, ABS brakes and premium Goodyear Endurance tires, this fifth wheel makes getting there almost as enjoyable as being there.
“We’ve built the 3900HBLR around the way people actually live and travel today,” said Curtis Gunter, general manager. “And because our team brings decades of experience and consistency to the table, we’re able to deliver both the quality and the peace of mind our customers deserve.”
